And this query fails with 500 status code and message “We’re currently experiencing some technical issues which our developers are working hard to resolve” (but the status page shows there are no incidents…)

So, the question is how I can set the correct value for columns for a new task?

Hey @xwizard – sorry to hear that you’ve found it difficult to get started with our API.

You can certainly use escape characters to make the column value string, but I recommend using GraphQL variables for this instead. It will let you send the column values as a normal JSON object and not worry about string interpolation.
